The Westminster Kennel Club Dog Show, founded in 1877, is a two-day breed show where each dog is judged according to how it conforms to breed standards. The show is held annually at Madison Square Gardens. The show is divided into seven groups including terrier group, sporting group, working group, non-sporting group, toy group, hound group and herding group. Each dog competes in its individual group then the group winners compete for the Best in Show award. The show is the second-longest continuously held sporting event in the US behind only the Kentucky Derby.
